Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A signal stall" for railroads including jaws to embrace the rails having shanks extending therefrom to provide operating pertions, and a signal hearing,- standard movahly associated. with said jaws to automatically clamp the latter on the rail, when the standard is dropped, said operating portions being actuated by movement o1 the standard in the opposite direction to disengage the jaws from the rail.

2. A signal staff for railroads including Leo /nee body is moved in one directii'in. the jaws being automatically expanded when the body is moved inthe opposite direction.

In testimony whereof I allix my signature in presence of two witnesses.
